I'm looking to get OpenFOAM solver of that case which was attached. I'm looking for get the dynamic solver when release load t>0. Any one have any idea about it?
If any please help me to simulate it.
I'm still new in openfoam to implement such cases. If any one have implementation such that cases, I'm looking for his/her reply.

regarding to the attached figure, I would like to implement the boundary conditions of that case for initial load when t = 0 and then to get the shape when release load for t>0. How could I get that in FSI solver?

Sorry, for bad description but only that I understood from my supervisor when he explained it to me.
